I actually watched it twice in the cinema and as with all good movies, you notice a lot of things only on the second go. I haven't had time to read up on imdb or wherever about people's thoughts on the movie, so reading this topic made me realize I got the ending completely differently than the creators intended. There's a time paradox which could have been avoided and that spoils it a little bit, but not much, because all in all, those things can't erase the brilliant human drama. The loneliness, yearning for home, for your loved ones, the pure fear but also courage...I find the Mann character completely realistic and plausible, especially in the begining, on 'his' planet. Stubbornly refusing to give up breaking the hatch and eventually going up in flames wasn't brilliant but is very plausible. Anyway, to the point. I thought the 5D space was created by miss Brand. As Cooper's time gets ever slower, she is out there, revealing planets and making it happen. Eventually his seconds last her years, and with the robot's data, she is able to build his 5D world in time before Coop is killed. Now, this obviously isn't true beacuse of at least two reasons, but I wish it was, because it gives TIME additional meaning (good point by someone that time might be the theme of the movie). It also puts less emphasis on the time paradox, because you kind of forget that they got there through the wormhole...made by long deceased, suffocated humans. An easy way out of that one could be that "underground people", Murph in particular, found a way to open the wormhole-there were possibly several iterations of time travel. Why do that if you're already that advanced? That's the easy part, save all those people.
Anyway, it had a lot of similarities to 2001, the terrifying silence, the terrible loneliness, incredible sacrifice, vastness, technical brilliance. All in all, 9/10.
